I'd like to upload Crypt::TEA (README appended), a module implementing
the Tiny Encryption Algorithm, to CPAN. Please suggest an alternative
name if Crypt::TEA is unsuitable.

NAME
Crypt::TEA - Tiny Encryption Algorithm
SYNOPSIS
use Crypt::TEA;
$tea = Crypt::TEA->new($key);
$ciphertext = $tea->encrypt($plaintext);
$plaintext = $tea->decrypt($ciphertext);
DESCRIPTION
This module implements TEA encryption, as described in
<http://www.cl.cam.ac.uk/ftp/users/djw3/tea.ps> and
<http://www.cl.cam.ac.uk/ftp/users/djw3/xtea.ps>. It supports the
Crypt::CBC interface, which supports the methods described below.
Functions
blocksize
Returns the size (in bytes) of the block.
keysize
Returns the size (in bytes) of the key.
new($key, $rounds)
This creates a new Crypt::TEA object with the specified key
(assumed to be of keysize() bytes). The optional rounds
parameter specifies the number of rounds of encryption to
perform, and defaults to 32.
encrypt($data)
Encrypts $data (of blocksize() bytes) and returns the
corresponding ciphertext.
decrypt($data)
Decrypts $data (of blocksize() bytes) and returns the
corresponding plaintext.
